This species is commonly found in boreal and mixed forests, temperate forest, bamboo and tree plantations, and abandoned orchard in mountain areas in Taiwan. It flies along trails, small logging road and edge of forests, and above small streams with dense canopy cover. It flies mostly in lower heights from near the ground to less than 1.5 m (Lee et al. 2007, Lu 2013, Y.-F. Lee, unpublished data). It is often found roosting on tree trunk, segments of dead stem of Oldhams' bamboo (Bambusa oldhamii), dead leaves of shell ginger (Alpinia zerumbet), Flying Spider-monkey tree fern (Cyathea lepifera), rice paper plant (Tetrapanax papyrifer), Japanese Cider (Cryptomeria japonica), long-leaf Chinkapin (Castanopsis carlesii), upright elephant ear (Alocasia odora), plantain (Musa uranoscopos) within forest, both dead and furled leaves of banana (Musa spp.) in plantations, and bat boxes (Chen 2011, Cheng et al. 2015, Chou et al. 2008, Chu et al. 2008, Ho et al. 2016). Individuals have been observed switching roosts at a distance of c. 100 m every 1-4 days (Chu et al. 2008, Chen 2011, Cheng et al. 2015). Insectivorous, its diet includes coleopterans, hemipterans, lepidopterans, neuropterans, dipterans, orthopterans, hymenopterans, and spiders (Lee et al. 2005, Lu 2013). A recent study suggests it uses both echolocation and chemical cues to detect prey and is capable of obtaining insects directly from object surface (Liao 2013). Females have been observed in pregnancy in April and May (Cheng et al. 2015), and lactating in May and June (Kuo, H.-C., Chen, S.-F., and Rossiter, S. personal communication).

This species is endemic to Taiwan (Kuo 2004) and widely distributed from low to middle high elevation in hill and mountain areas on the island (Kuo et al. 2014).

There are no known conservation measures in place for this species. This species occurs in several protected areas, including the Kenting National Park, Yangmingshan National park, Shei-Pa National Park, Taroko National Park, and Yushan National Park (Lee et al. 2007, Lee and Huang 2007, Ho et al. 2016, Cheng, H.-S. and Chou, C.-H. unpublished data). Research is needed in the fields of population status, biology and ecology, habitat status and threats.
